IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 142,742, datedSeptember 9, 1873; application filed July 21, 1873.

To all whom it may concern:

Be it known that 1, CHARLES W. SHERER, of Chicago, in the county of Cookand State Illinois, have invented certain Improvements inWashing-Machines, of which the following is a specification:

This invention relates to that class of washing-machines in which thegarments to be washed are passed between fluted rollers; and the presentinvention consists in employing a central roller, to which is appliedthe power, and a series of overlying rollers, surrounding the central,said overlying rollers being pivoted in a hinged weighted framework, andadapted to slide up and down all together in a slide-way, to adapt themtovarious thicknesses of goods or garments. The advantage of having therollers swing in a weighted frame over the use of springs consists inthe fact that, when springs are compressed, the pressure they exertincreases, so that when a thick or folded piece of cloth or garmentpasses through between spring-compressed rollers it receives a greaterpressure than a thin or unfolded piece would; while the weighted framealways exerts the same pressure, which pressure may be gaged to exactlythe right amount to allowthe cloth to remain saturated always with suds,no matter how thick or how thin; and the invention further consists inthe peculiar construction and combination of parts hereinafter morefully explained.

1n the accompanying drawing, which forms a part of this specification,Figure l represents a side view of my improved washingmachine. Fig. 2 isa top or plan view of the same. Fig. 3 is an end view thereof.

Like letters of reference, made use of in the several figures, indicatelike parts wherever used.

To enable those skilled in the art to make and use my invention, I willproceed to describe the same.

In said drawing, A represents the supporting-frame of the mechanism, bymeans of which it may be applied to a common washtub. B is the centralfluted roller, carried by the shaft 0, having bearings in the said I) isthe winch or crank, by

which said central roller is turned. Attached to the standards of themain frame at each end is a guide -plate, 'E, made with a central slotto receive and retain the ends of the shaft 0, upon which or with whichthe upper central roller F turns. This upper central shaft 6 serves alsoas a pivot, upon which swing the parts of the weighted hinged framepieces G G. These frame pieces are connected together by rods or shaftsf, upon which are placed rollers F like the roller F. I prefer to havethese upper rollers F F five in number, as that number produces the bestresult at the least expense. The pieces G G are weighted, or are made ofsolid metal, large enough to give them proper weight, as shown in thedrawing. The rods f and 0 connect the frame G G together so strongly asto prevent any torsion or twist when raised by the clothes passingbetween the rollers. To the outer ends of the shaft or rod 0 are affixedthe buttons h h, which are made with rockerends, as shown at c, so thatone end of the upper system of rollers may be raised higher than theother without the buttons binding. The upper system or are of rollers FF move together, and rest upon the cloth to be washed, which is fedbetween said system and the central roller B, upon which the arc ofrollers rests.

Having thus fully described my invention, that which I deem new, anddesire to secure by Letters Patent, is

1. The are of fluted rollers F F, bearing in the hinged weighted framesG G, in combination with the central roller B, substantially asspecified.

2. The hinged weighted frame pieces G G, connected together by the rigidrods 0 f, upon which turn loosely the rollers F F, asspecified.

3. The are of fluted rollers F F, bearing in the weighted frame G G, incombination with the rocker-shaped buttons h h, attached to the ends ofthe rod 0, and the upright slotted guide-plates E, as specified.
